Apple’s automagic GPU switching technology explained

Although Apple has made it perfectly clear it will not enable multitasking on the iPhone 3G due to “hardware limitations” (specifically its 128MB of RAM and 400MHz processor), iPhone hacker cdevwill quickly discovered that an unbelievably simple modification of the N82AP.plist will enable multitasking on the iPhone 3G. And wouldn’t you know it, today a video was posted to YouTube which shows an jailbroken iPhone 3G with the modified .plist running multitasking as if it were no big deal. While it’s tempting to say Apple is simply restricting multitasking to the iPhone 3GS and up for the sake of hardware sales, it must be remembered that the APIs which actually allow for processes to run in the background are not implemented in any of the applications running in the video. In all likelihood, simply streaming music from Pandora while switching between playing Doodle Jump and firing off some tweets would likely bring the iPhone 3G to its knees. We mean, just look how painfully long it takes to open up the Clock application. But that’s just our take. Check out the video after the jump and let us know yours.
